Given the system:
3x + y + z + v = b1
x - y + z + v = b2
x + y - z + v = b3
x + y + z - v = b4
Fint the values for b1,b2,b3,b4 for which the system is consistent, in the form:
a1 * b1 + a2 * b2 + a3 * b3 + a4 * b4 = 0
and the answer is the row vector [a1,a2,a3,a4].
Solve the system with the values previously found, in the form:
|x| | b1 |
|y| | b2 |
|z| = C | b3 | + t * d
|v| | b4 |
Thanks!
